SOAP-FLAKER.

SPECIFICATION forming part of Letters Patent No. 739,175, datedSeptember 15, 1903.

Application led May 22, 1903. Serial No. 158,324. (No model.)

To all whom it may concern/.f

Be it known that I, WILLIAM G. HAWLEY, a citizen of the United StatesofAmerica, residing in NewYork city, county and State of New York, haveinvented an Improved'Soap- Flaker, of which the following is aspecification.

This invention has for its object to improve the construction of soapliakers or shavers for lavatory use, so that they can be cheaplyconstructed, readily operated, be of sightly appearance, and beconvenient for use.

In the accompanying drawings, Figure lis a sectional elevation on theline 1 1, Fig. 2. Fig. 2 is a sectional front view of the soapflaker onthe line 2 2, Fig. 1. Fig. 3 is asection of the back of the case on theline 3 3, Figs. 1 and 2. Fig. 4 is a sectional view of the soap-shavingcylinder detached. Fig. 5 is a sectional view of a modification, andFig. 6 is a plan View of the upper end of the feedscrew.

The main frame of the device comprises a fixed part in the form of abackplate C and a cylindrical inclosing casing B, hinged at K to theback plate C, which latter is mounted upon astandard N, suitable forattachment to the top plate of a fixed Washbasin. Through an opening inthe front of the inclosing casing projects the closed front face of thesoapshaving cylinder A, which is shown separately in Fig. 4. Thisshaving-cylinder A is separable from the back plate and is provided withan outwardly-projecting rim or flange A at its inner open end. lTheouter surface of this iiange is fitted into a bearing in the outercasing B, and the ange is held in position when the casing is closed andlatched or locked, as at l, by means of an inwardlyprojecting liange orshoulder-b in the outer casing and an annular projection o, on theinside surface of the back plate C. A bearing is thus formed in whichthe shaving-cylinder can be rotated within the outer cylinder by meansof a projecting handle h on the front of the shaving-cylinder.

The shaving-cylinder has a series of knives M at its periphery or sidewalls, and these, knives may conveniently be formed out of the sheetmetal of the cylinder itself, as by slotting the cylinder at m andbending the following edges of the slots inward, as shown in Fig.2Between the shaving-cylinder and the outer casing B an annular space isformed about the knives, intowhichthe soap shavings pass as they are cutaway and fall to the bottom of the space, where a discharge-outlet c inthe casing is provided.

To hold the cake of soap in place, I form on the inner face of the backplate sharpedged vertical ribs or guides D D, and I also secure to theback plate a curved springplate P, the free end of which projectsdownwardly, Figs. 1 and 2, and presses against the front face of thecake of soap, which is thereby pressed into holding contact with theribs D D, as indicated by dotted lines in Figs. 1 and 2.

To keep the soap up to the inner face of the cylinder or to provide forthe feeding forward of the soap cake to the cutting-knives as the soapis cutaway, I prefer to use a feedn screw S, mounted in bearings e e inthe back plate and having its thread engaged with semicircular threadsat the diagonal upper and lower parts of the bore of a feed-nut F, whichis suitablyguided in the back plate and bears upon the soap cake, asshown in Fig. 1. To turn the feed-screw, I provide at its upper endstuds s s, with which engages a spiral groove or thread a on the innerface of the 'rim A of the revolving cylinder A. The diagonally oppositeparts of the hole through the feed-nut F are cut away, as shown in Fig.1, to permit the nut to be run back by hand toward thestarting end ofthe feedscrew S, a Well-known expedient. Instead of using a feed-nut,however, I may form, upon the screw itself, as at S', Fig. 5, adeep andsharp-edged thread, which may engage the soap cake itself to feed itforward.

The feed-screw is located atone side of the center of the casing, asshown in Fig. 2, and so arranged that the spiral or thread on ltheshaving-cylinder will engage with the studs on one side of thefeed-screw and clear those on the opposite side. The arrangement andproportioning of the spiral, the studs, and the hinge K are such that inopening the casing to replace the soap the spiral, which falls away fromthe casing and knives, will draw the stud with which it is engagedthrough a fraction of a revolution and then freely disengage, so thatthe casing and shaving-cylinder may be withdrawn from the back platetogether. In closing the casing a similar action in the reversedirection takes place.

I claim as my invention- 1. A soap-ilaker, comprising a casing having adischarge-outlet, a rotatable cylinder having knives located in itsperiphery within the cylinder, stationarymeans for holding the soapwithin the cylindei` and means for feed` ing the soap to the knives,substantially as described.

2. A soap-aker, comprising a plate with sharp projecting guides, aspring adapted to force the soap against the guides and a feeding deviceadapted to feed the soap in the direction of the guides, substantiallyas described.

3. A soap-shaver, comprising a plate, a casing, a rotatableknife-cylinder within the casing, a device for holding and feeding thesoap to the knives Within the cylinder and means for operating saidfeeding device by the rothe casing and gearing between the rotatableknife-cylinderand feed device, substantially as desebed.

In testimony whereof I have signed my name to this specicationin thepresence of two subscribing witnesses.
